An analysis of coherent digital receivers in a jamming environment.
analysisofcohere00farw.pdf (6.285Mb)Abstract
The effect of various jammer waveforms on known optimum
coherent digital receivers is analyzed and evaluated in
terms of receiver performance. The optimum jaaner waveform
for the specified receiver is derived and several jamming
strategies are studied and compared to the optimum case.
These jammer waveforms strategies include deterministic
models of tonal, weighted signals, frequency moiilated, and
additive white noise jamiers. An M-AR5T digital coherent
receiver using orthogonal modulation (FSK) , is subjected to
various jammer waveforms and the receiver performance
analyzed. Graphical results based on numerical inalyses are
presented to show the effects of jammer waveforms on
receiver performance.
